MECHANICAL TIE TAMPER. I

Application filed November 19, 1925. Seriall No. 69,952.

To all whom it may concern. Be it known thatI, WILLIAM H. ARM- STRONG, a citizen of the United States, and a resident of Plainfield, county of Union, and State of New Jersey, have invented a certain Mechanical Tie Tamper, of which the following is a specification accompanied by drawings. r V

This invention relates to tamping bars and has for its objects to enable material to be tamped under ties and in similar places with great force.

It is also an object of theinvention to enable power to be applied to the tamping bar in a convenient manner. Other objects and advantages of the invention will be in part obvious and in part pointed out hereinafter. In the drawing in which similar reference characters refer to similar parts, Figure 1 is a perspective view of a tamping bar constructed in accordance with the practice of the invention and shows the manner in which it is employed, I Figure 2 is a perspective view of a modified form of the invention,' Y

Figure 3 is a view in perspective of a second modified form of the invention, and

Figure a is a perspective view of the modi fication shown in F gure 3 indicating the manner of its handling and operation.

Referring to the drawings and more par- 7 ticularly to- Figure 1 the tie tamper consists of a bar-A. having a tamping end B transverse to the length ator and a shoe D pivotally attached by means of a link E to the bar A. The link E two upwardly projecting ears F by means of a pin G and is provided with forked ends H between which the bar A passes and is attached by means of a pin J.

The shoe D is adapted to rest upon a. tie K adjacent the tie L which is to be tamped and acts as a brace to bear against as the ballasting material is being thrust under the t-ie'L bythe'tamping end B. To this end the shoe Dis provided with a. downwardly extending portion 0 at right angles to the main body of the shoe by means of which the tie K is gripped.

In operation, such as indicated the shoe D is placed on a tie of the bar, afihandle C which is adapted to be grasped by the operv at K and adjacent the tie L which is to be tamped. The operator grasps CITY, new ansnv, A' 'oonronArron or nnwj J the handles and, with the pin as crum, drives therook or other ballast mate-.-,

rial beneath the tie L by meansof the tamping end B. Fortamping ties which are spaced farther apart or nearer together than i normally, extra holes P are provided in the forked ends H of the link E by means of which the distance from the pin J to the pivot G may be suitably lengthened or short-.

ened for convenience in manipulating the handle 0., The operator may stand'upon the flat portion of the shoe D in order to steady it while tamping.

In the modification shown in 'FigurefZ, a bar Q, provided with suitable tamp-ing ends R and a handle S is pivoted directly ona shoe T, A longitudinal slot U is provided in the bar Q, which permits sliding movement of the bar on a pin V mounted in a. forked l 'l t W of the shoe T. As in the above described embodiment of the invention'the shoe T is adapted to reston the tie K which takes the thrust from the bar Q, as the operator presses against the handle S. The oper- 1 v ation of this form of invention is similar to that above describedQ The shoe T is adapted to receive the weight of the operator as he.

manipulates the tamping end- B by means of the handle S. Swinging movement of the barQ, takes place about the pin B asa fulcrum while vertical or longitudinal movement of'the bar Qis permitted by the sliding of thepin D in the slot U.

In the embodiment illustrated in Figures 3 and 4 the ftamping apparatus'comprises a 'shoe X provided with a link Y pivoted at Z on the shoe X. A bar I) is pivotally attached to the forked end 0 of the link Y and is provided with a handle cl at which the forceis applied. The end of the bar I) is forked as at e and is provided with a pin f to engage a hook-shaped bar 9 provided with a slot '72.

The end ofthe member 9 is attached by means of links j to the bar (Z. I

Downward pressure against the ber' g by means of the links j and provides additional leverage to force the tamping end g handle 65 forces the tamping. end icon the hook-shaped- 70 under the tie L. The form of camping bar shown in Figures 3 and 4 is relatively compact andprovides greater leveragethan the forms above described.

' I claim 1. -Ata1'nping bar comprising ashjoe adapted to rest on a tie, and a bar pivotally mounted on said shoe for independent swinging and vertical movements to tamp ma terlal under an adjacent tie.

2. A tamping apparatus comprising afshoe I having. anguiarly dlsposed portlons to grip 'plvotally mounted on stud a tie, and a bar shoe for. independent swinging and vertical ed on said forkedex'tension and ali tallyettached to sald hnk having movements adapted to temp material under an ad aCent tre 3. A tamping apparatuscomprisinga shoe having angular-1y dlsposed portlons adapted to" rest on and grip a tie, a forked extension on said shoe, 1 link membetpivotally mount- WILLIAM HAROLD ARMSTRONG.
